To all whomz't may concern.'

Be it known that I, THOMAS GWEN- BATES, a subject of the King ofEngland, and residinof at Liverpool, in the county of Lancaster, ngland,have invented Improvements in Machinery for Making Wafer Biscuits, CupWafers, and Similar Articles from Liquid, of which the following is aspecification.

This invention has reference to machinery for making wafer biscuits, cupwafers, and similar articles, and it relates more particularly to thattype in which a plurality of cooking plates are connected in series, andare passed through an oven with the biscuit material enclosed withinthem, and then brought out of the oven after cooking, and opened, andre-Oharged with batter or like material, and closed, and the operationrepeated; in which type of apparatus, in some cases, the plates are runon tracks one below the other in entering, and returning from the Oven,which may be heated by gases or other heating medium.

In a machine according to this invention, between the adjacent edges ofeach set of plates, there is introduced a shield or separating medium,ywhich prevents the steam generated from the batter or materialintroduced into a hot plate, after charging, issuing from same betweenthe upper and lower plates, just prior to closing, from blowing battertherefrom into the open succeeding plate on reaching it; and thispartition or shield, the sides of which the adjacent ends of the twoplates may practically touch, may be of an inverted U- type-*say ofmetal-carried by brackets or arms on the inside of the plate connectinglinks or devices. These arms or brackets extend inwards horizontally orsubstantially so, so as to be in line with, or in the same plane as theaxles of the plates in order to clear the lower track rails of themachine, as they move along the track and turn round at the ends, andthe inward ends of the arms or brackets project upwards into theshields, and are connected by pins say to same; lmovement longitudinallybeing allowed so as to compensate for expansion and contraction.

The invention is illustrated in the annexed drawings, in which Figure 1is an end view of the machine showing a partition or shield; Figure 2 isa cross section of the shield; Figure 3 is a side elevation of themachine; and Figure 4 a plan.

Referring to the drawings, 1 and 2 are the upper and lower plates of themachine, the upper one of which is hinged at 3, and these plates areeach mounted on to cross shafts 4 fixed to the lower plate, and havingwheels 5 on their ends which run on tracks 6, on the inside of the mainframes 7 of the machine; the axles of the successive plates beingconnected together by coupling links 8 which form couplings between theplates.

The machine thus far described in connection with the drawings is ofknown construction.

The shield or partition is marked 10, and

it is carried by brackets 11 fixed on the inner sides of the couplinglinks 8, and the form of the partition or shield is an inverted narrowtrough of sheet metal, as seen in Figure 2, and the heads of thebrackets ll lie within the ends of the shield, and the shield is securedto the brackets by rivets or the like, longitudinal movement beingallowed by giving freedom of play in the connections, so as to allow forexpansion and contraction. In the machines of the kind referred to, asheretofore made, comprising a number of plates successively charged withmatter or fluid after the cooked articles have been removed, the platesbeing hot (and being heated by gas or other means in the known way), thebatter begins to boil before the upper cover 1 comes down and is closed,and the steam issues in a thin stream from the rear edge of the newlycharged plate, (as well as other edges), and this stream of steam ishorizontally projected on to the leading open edges of the next platesbeing charged with batter, and this batter isblown about by the steam,and often a large proportion lost; but by the present invention, thebatter being so introduced is not interfered with and cannot be blownaway, being prevented by the shield or partition I0 between the plates.

What is claimed is 1. In a wafer biscuit making machine, a movableseries of plates, and a bafie interposed between adjacent plates toprevent a fresh charge introduced in one set of plates from beinginterfered with by steam generated from the charge oi the precedingplate, said baille projecting above the material receiving plane of theplates and being Wholly free of connection with any of the plates.

2. In a Wafer biscuit making machine having a movable series of plates,an i11- verted U-shaped metallic member interposed between adjacentplates of the series lo to prevent a fresh charge introduced in one setof plates from being interfered lwith naine to thisspeciication in thepresence 15 of two subscribing Witnesses.
